Embodiment 1
[0070] The invention provides a naked-eye 3D image display device, which can be realized by more than two display screens. The embodiment of the present invention takes two display screens as an example to provide a naked-eye 3D image display device, such as figure 1 As shown, the device includes:
[0071] 2D / 3D converter, depth of field processing control module, infrared sensing module and at least two display screens.
[0072] This embodiment takes two display screens as an example to introduce in detail, that is, the display device includes a first display screen and a second display screen, the first display screen and the second display screen are overlapped, and the second display screen is larger than the first display screen. screen away from the user.
[0073] The 2D / 3D converter is used to convert ordinary 2D signals into 3D stereo signals. The basic principle of the 2D to 3D conversion function is to analyze the 2D scene, outline and highlight the close-range ima...
Embodiment 2
[0082] An embodiment of the present invention provides a naked-eye 3D image display device. The modules included in the display device in this embodiment are the same as those in the first embodiment.
[0083] Further, the display device also includes a third display screen. While increasing the number of display screens, the overall thickness of the display device is also increased, which enhances the effect of 3D stereoscopic display and makes the effect of 3D stereoscopic display more realistic and ideal.
[0084] Further, the depth-of-field processing control module is used to calculate and separate the 3D stereo signal into a first signal, a second signal, and a third signal, and perform depth-of-field processing on the first signal, second signal, and third signal according to the infrared sensing distance signal. processing, and send the depth-of-field-processed first signal, second signal and third signal to the first display screen, the second display screen and the t...
Embodiment 3
[0089] An embodiment of the present invention provides a naked-eye 3D image display method. In this embodiment, a display device having two display screens is used as an example to describe in detail, that is, the display device includes a first display screen and a second display screen.
[0090] Such as Figure 4 As shown, the display method includes:
[0091] In step 101, the 2D / 3D converter converts ordinary 2D signals into 3D stereoscopic signals.
[0092] The basic principle of the 2D to 3D function is to analyze the 2D scene, outline and highlight the close-range image in the scene, and at the same time put the distant view image in the back, for example, people, etc. in the front, background environment and objects in the back; further In this way, the front part of the same object is fronted, and the rear part is reared, so that the 2D image can be transformed into a 3D effect in real time.
[0093] Step 102, the depth of field processing control module calculates and...
